Both centimeters and millimeters are units of measurement for length, where 1 millimeter is equal to 0. 1 centimeter. Therefore, to convert millimeters into centimeters, just divide the number of millimeters by 10, for example, 130mmm ÷10 = 13cm, so130mm is equal to13cm.
In daily life, we often need to change the length. For example, when buying goods, the size of the goods is often expressed in centimeters or millimeters. If you want to know the actual length, you need to convert it into familiar units. At the same time, scientific experiments or other occasions that need accurate measurement also need length conversion to ensure the accuracy of measurement results.
It is worth noting that for larger units of length, such as meters or kilometers, we need to convert centimeters or millimeters into larger units. For example, 1 m equals 100 cm, then 130 mm equals 0.13 m.
Millimeter usage scenario
1. In manufacturing or processing industries, dimensions are usually marked and measured in millimeters. Such as parts of mechanical equipment, parts of electronic products, parts of vehicles, etc. , all need to be accurately measured and manufactured in millimeters. The use of millimeters can ensure the machining accuracy, reduce the machining error rate and ensure that the products meet the specification requirements.
2. In the medical field, millimeter is also an important unit of measurement. For example, doctors will use millimeters to measure patients' blood pressure, body temperature, leg length and so on. Various medical equipment, such as sphygmomanometer, blood glucose meter, needle tube, infusion tube, etc. In the production process, it is also necessary to accurately divide and manufacture according to millimeters.
3. Millimeter also plays a very important role in home decoration, architectural design and construction, art production and other industries. For example, when decorating a home, you need to measure the wall size of the house, draw a floor plan and so on; When building design and construction, the building structure should be formulated according to the millimeter standard and drawings should be drawn; In the field of artistic production, it is necessary to measure, draw and make objects in strict accordance with millimeters.
